On a 9016GVG1, which screw is the main adjustment screw and which is the differential adjustment screw?

Product Line:
9016 vacuum switches 

Resolution: 
Per Instruction Bulletin 65013-101-25, set the large nut first which adjusts the cut out range. Both the high and the low pressures will change as this nut is adjusted, but the difference between the two will remain fixed, the change in cut-in point following the change in cut-out at the distance determined by the differential setting. Then the differential is set with the small nut which adjusts the difference between cut-in and cut-out, the cut-in remaining fixed, and only the cut-out varying. Separation between cut-in and cut-out increases as the differential nut is rotated clockwise, increasing as the nut is rotated counterclockwise.
